When using the nvidia driver, nVidia cards have the best Xv acceleration of
any card out there. The FX 5200 is a bit faster than an MX card, for not
much . It isn't anywhere near being a hardware decoder, but helps
considerably. Then there's XvMC, which does even more to accelerate video
decode and display, much closer to being an actual hardware decoder, but not
quite, and not entirely stable with HDTV. Or something like that.
I'm not certain on the FX series, but for the 4 MX series, it actually said in
the product pages that there was a hardware mpeg2 decoder. I *think* that's
in the FX also. Support just isn't fully implemented in the Linux driver
though, all we've got is XvMC, which I believe may interface with it on some
level, like how the Unichrome XvMC driver interfaces with the cle266 decoder.
A certain someone who works at nVidia might be able to clarify things better
than me though...
